Unveiling the strategies of bacterial adaptation to stress constitute a challenging area of research. The understanding of mechanisms governing emergence of resistance to antimicrobials is of particular importance regarding the increasing threat of antibiotic resistance on public health worldwide. In the last decades, the fast democratization of sequencing technologies along with the development of dedicated bioinformatical tools to process data offered new opportunities to characterize genomic variations underlying bacterial adaptation. Thereby, research teams have now the possibility to dive deeper in the deciphering of bacterial adaptive mechanisms through the identification of specific genetic targets mediating survival to stress. In this chapter, we proposed a step-by-step bioinformatical pipeline enabling the identification of mutational events underlying biocidal stress adaptation associated with antimicrobial resistance development using Escherichia marmotae as an illustrative model.
揭示细菌适应压力的策略是一个具有挑战性的研究领域。了解对抗生素耐药性产生的机制对于全球公共卫生领域日益严重的抗生素耐药性威胁尤为重要。在过去的几十年中,测序技术的快速普及以及专门的生物信息学工具的发展,为研究细菌适应的基因组变异提供了新的机会。因此,研究团队现在有可能通过鉴定介导压力生存的特定遗传靶标,更深入地研究细菌适应性机制。在本章中,我们提出了一个分步生物信息学管道,使用 Marmota 埃希氏菌作为说明性模型,用于鉴定与抗生素耐药性发展相关的杀菌应激适应中的突变事件。
